T all whom it may con/067%:

Be it known that I, W'ILLIAM BETZ, a citi' zen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Fodder-Cutters; and I dohereby deolare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making` a part ro of this specification, and to the letters of referencemarked thereon, in which- Figure 1 is an isometrical View. Fig. l is aView of the presser-foot. Fig. 2 is a side View showing' parts insection and parts rer 5 moved. Fig. 3 is a side elevation. Fig. 4 is adetached view of one of the fodder-cutter knife-arms. Fig. 5-is adetached vview of the fodder-cutter bar. t

The present invention has relation to fodzo der-cutters; and it consistsin the different parts and combinations of parts hereinafter described,and particular] y pointed out in the clams.

Similar letters of reference indicate corre- 2 5 sponding parts in allthe figures of the draw- V ings.

In the aecompanying drawings, A represents the side bars, which arelocated substantially as' illustrated in the drawings, and

are held in the desired position by means of suitable cross-bars. Theseside bars are supported at the required heig'ht by means of suitablelegs properly framed and braced to the side bars A. The cutter-shaft Bis located 3 5 as illustrated in the drawings, and is journaled on' theside bars Aby means of the boXes a. To the shaft B are securely attachedthe arms b, said arms being located spirally to the shaft. The arms bare provided with 40 the grooves c, which are for the purpose ofreeeiving` the shanks of the knives O. These grooves c are located uponopposite sides of the arms Z), for the purpose hereinafter stated. Theknives C are substantially of the form shown, and, as shown, are bent attheir cutting` ends at an angle to their shanks. To each arm b twoknives O are attached, as illustrated in the drawings. The angleportions of these knives C are bent or turned in opposite directions,therebyproviding' a right and left cutting-knife upon each arm Z), andfor the purpose of bringing the knives O in proper cutting positions.

The cutter-bar D is located substantially as shown in Fig. 1, and isprovided with the V-shaped teeth. For the purpose of cansing the knit'esO to cut easly, the teeth d are bent or curVed np, as illustrated inFig. 5, thereby producing a shear cut as the knives O pass between theteeth d. The knives C and the cutter-bar D are designed and calculatedto cut cornstalks and like material. For the purpose of adjusting theknives C to or from the cutter-bar D, the slots d' are pro- `vided, saidknives being secureh1 held at the desired point of adjustment by meansof the clamping'-bolts (12. To the shaft B is secnrely attached thepinion c, which is for the purpose of communicating' rotary motion tothe idler The idler f is for the purpose of communicating rotary motionto the idler g, which communicates rotary motion to the wheel h, whichwheel is securely attached to the shaft 71/, upon which shaft the lowerfeedroller is attached. Upon the shaft h' are 10- 75 cated and. securelyattached the sprocket- Wheels h, said sprocket-wheels being locatedlsubstantially as illustrated in the drawings,

and, as shown, these sprocket-wheels 72,2 are located in line with thesprocket-wheels G and J.

The top or 'upper feed-roller E is located substantially as illustrated,and is so arranged that it can move up and down in the slot F, its shaftbeing' free to slide up and down in said slot. The shaft' of thefeed-roller E is provided with the sprocket-wheels G, which are for thepurpose hereinafter descrbed.

The spring-bars H are attached to the crossbar H' or its equivalent inany convenient and well-known manner. (But one of the spring-bars isshown in the drawings.) To the free ends of the spring-bars H isjournaled the shaft I, and to this shaft are securely attached thesprocket-wheels J.

The drive-Chains are located substantially' as shown, and, as shown,they engage the sprocket-wheels hg, thereby communicating motion to ,thetop or upper feed-roller E by` means of the drive-Chains K, engagingwith Iol the sprocket-Wheels 712.

It will be seen that as the upper feed-roller moves up and down it willcause the sproeket- Wheels J to move With said feed-roller E, thedrive-Chains K being' held tight by means of the weight of the shaft Iand the sproeket- Wheels J and the reaetion of the spring-bars H. Forthe purpose of regulating the tension of the spring-bars IIscreW-threaded bolts K' are provided. (But one of the bolts K' is shownin the drawings.) The wheel P and crank P' are attached and located asshown when it is desired -to turn the machine proper by hand. For thepurpose of preventing the fodder from springing or jumping the presser-'foot D3 is provided, which is attached to the w arms D' which arms areattached at their top foot is located in front of the bar D, as shown inFig. 1, and extends to Withina short distance of the teeth (l. If it isdesired, a small roller may be properly journaled to the arms D',

which takes the place of the presser-foot D2. J

2. The spring-bars H, having' journaled to the free ends thereof theshaft I, provided with the sproeket-Wheels J, the drive-Chains K,adapted to eng'age the sproeket-wheels J, 77,2, and G, and thesprocket-wheels 712 and G, substantially as and for the purposespecified. In testimony that I claim the aboveI have hereunto subscribedmy name in the presenee of two witnesses.
